I always said all bets were off if Kurzweil ever puts out an arranger. Don't want to hear about using it as a controller with a BK-7m or MidJay, I'm sure that would be dynamite too, but I'm talking about a stand-alone arranger to rival s950/Tyros5, PAx4/PA800 or even G-70/BK-9. I've owned a PC 88, a SP3 and a Mark 5; there are no better sounds and OS to be had.
